“I deeply regret the comments I made about Mick in the WSJ which were completely out of line,” Richards wrote. “I have of course apologized to him in person.”

In an interview with WSJ Magazine (via the New York Post), Richards said of Jagger — who welcomed an eighth child at age 73 in 2016 — “It’s time for snip. You can’t be a father at that age. Those poor kids!” Jagger is now 74.

This isn’t the first time that Richards has apologized after tearing into his longtime bandmate. After calling Jagger “unbearable” and accusing him of being poorly endowed in his 2010 autobiography “Life,” Richards apologized in 2012, telling Rolling Stone, “As far as the book goes, it was my story and it was very raw, as I meant it to be, but I know that some parts of it and some of the publicity really offended Mick and I regret that.”

I deeply regret the comments I made about Mick in the WSJ which were completely out of line. I have of course apologised to him in person.
